In each of the 100 cases in this study (and in all cases thereafter) instillation of phenylephrine into the 'chemically sympathectomized' eye resulted in prompt and complete reversal of the eye signs and symptoms that invariably follow effective stellate ganglion block. Not only did the conjunctival and scleral injection disappear, the ptotic upper eyelid also returned immediately to a normal or even slightly retracted position. Over the next 10 to 15 min, the miotic pupil returned to its normal size, and the nasal congestion produced by the block similarly decreased and then disappeared.
